What Makes Us Different?
Our OpticalFusion™ Technology (comprises of multiple LED and Photodiode pairs) effectively removes motion noise and results in very accurate physiological signals such as dynamic heart rate, interbeat intervals (RRI) and motion (including vertical oscillation, left/right foot contact time and gait) etc, so that the results can be useful for sports, healthcare and even medical applications.
We probably have the world’s smallest heart rate sensing technology when applied to earphones, this results in consumers finding our customers’ earphones very comfortable to wear. Check out the Anker Liberty 4, Sanag Apex, Hera Leto M8, Otozabu R6 Pro OWS earbuds and Zovimax Euno 9 sleep earbuds
